Ben McKenzie has praised his Southland co-star Michael Cudlitz for helping to promote the show.

Speaking to Just Jared, the former O.C. actor said that the series might not survive without Cudlitz's interactivity on Facebook and Twitter.

"He is a tireless advocate for the show. He does it all - he tweets, he does Cudlitz Corner. He loves it as much as any of the rest of us, if not more so, so it's great," he said.

"I think that interactivity is great - TNT is a little ahead of the curve in terms of embracing the new paradigm of Facebook pages and web chats - we did a full cast webchat for the premiere of the show - and having fan screenings all over the country."

He added: "It's cool - I think a show like ours is only going to survive by having people talk about it because we’re not just going to be able to draw them in on a weekly basis with a marketing campaign - it has to be person to person."
